- ItemOpen AccessThe Use of Real-Time Feedback to Improve Kinematic Marker Placement Consistency Among Novice Examiners(2017) Macaulay, Charles Andrew John; Ferber, Reed; Jacob, Christian; Edwards, Brent; Duffett-Leger, LindaMarker placement deviation contributes the largest amount of error in gait kinematic data. The study purpose was to determine whether a novel, real-time marker-placement tool could improve consistency of gait kinematic data. Twelve novice examiners placed retroreflective markers on a single runner. For each examiner, a running trial was analyzed using two static trials: (1) PRE and (2) POST implementation of the feedback tool. The protocol was repeated a second time, one week later, resulting in PRE1, POST1, PRE2, and POST2 conditions. The 95% confidence interval (CI) of the mean joint angles for the entire stride, was compared between the PRE1/POST1, and PRE2/POST2 conditions. POST1 feedback trials showed a reduced 95%CI range for eight of nine joint angles compared to PRE1. POST2 trials reduced the 95%CI for five of nine joint angles compared to PRE2. The results indicate a real-time feedback tool improves kinematic marker placement consistency for novice examiners.
